Title: Looking for DRAM 1MB Simms (100 NS or faster)
Post by: hamtronix on July 06, 2007, 08:44:43 PM

I was wondering if anyone had 6 DRAM 1MB Simms they would be willing to part with? Let me know by PMAIL if you do and how much you would charge + shipping to United States South Carolina 29403... Thanks, as always you rock!

Do you mean pre P2/2 30 pin SIMMs? I think I have a large stack at work, can take a look on Monday.

The RAM I am looking for is for my GVP SCSI card. I think it is 30 pin. Here is the info I can get from the manual:

Page Mode DRAM SIMM (100ns or faster) 1Mx8 SIMM. 8 individual DRAM chips soldered to a small circuit board. Counting the pins on the two illustrations in the manual there are 30 of them.

Thats as much info as I have. Thanks for the reply!

30 pin SIMMs are 8 bit wide each, so they must be installed in pairs for the required 16 bit bus width.

GVP had special, 32 bit wide SIMMs, but I think they were used only on accelerator boards and not on SCSI adapters. Take a look at BBoAH (http://www.amiga-hardware.com/), it might have additional information.
